Hardness ions, calcium and magnesium build up on piping, heat exchangers, water heaters, boilers, auto-claves, steam generators and any other steam related equipment. The scale buildup impedes water flow resulting in costly repairs, increased energy consumption, and clogged heat exchangers and boiler tubes. The life of linens, clothing, appliances and fixtures is also greatly reduced due to these "hard" minerals.

Softened water is also used in many process applications such as the production of cleaning agents and chemical production. For laundry and dish washing, the use of a water softener will significantly reduce the amount of soaps and detergents, resulting in reduced operating expenses.

The following facilities are examples of ideal applications for water softening equipment:

• Apartments/condominiums
• Boiler feedwater
• Car washes
• Food processing plants
• Hospitals
• Institutions
• Laundries
• Manufacturing plants
• Office complexes
• Restaurants

Our complete range of water softeners have single unit flow rates from 0.5-925 GPM. Higher flows can be treated using multiple units.

Offsite Regenerated Rental

Nalco PTS maintains an inventory of water softening resin available for temporary or permanent installations.  Temporary water softener systems are most commonly installed during a planned or unplanned shutdown for maintenance or repair of the in house water softener.  Water softener exchange systems are commonly used in areas where brine discharge is not allowed or for batch treatments of a custom product.
